Unable to install R2020 in Ubuntu

I am trying to install Matlab on a new Ubuntu machine.

I followed the instructions and download the file matlab_R2021a_glnxa64.zip.

sudo unzip -K -X matlab_R2021a_glnxa64.zip -d matlab_installer

cd matlab_installer2

sudo su

xhost +SI:localuser:root

sudo ./install

This resulted in the error below:

terminate called after throwing an instance of 'std::runtime_error'

what(): Unable to launch the MATLABWindow application. The exit code was: 127

Aborted

Based on the information I found on the internet, I removed files libfreetype.so.6.16.0 and libfreetype.so.6 from /bin/glnxa64 folder and then sudo ./install.

This time the program ran and matlab GUI opened. But the problem is that I can only enter my email address in the appropriate box. I can not enter the password (the cursor does not appear in the box and no characters are shown as I type the password). There is a problem with entering the password into the GUI box.

Thanks,

Vahid Hesany

You mentioned R2020 in the title but while running the command, you are specifying R2021a. Please verify the version which you want to download.

Another odd thing is that you cd to a different folder than you unzip.

That was just a typo. I unzipped to a new folder each time I tried a new debugging approach

Parth, the Matlab web site allows me to download different versions for year 2020 and 2021. I first download version 2020a and that didn’t work. Then I tried 2021, and the same problem persisted.

I bought a Matlab home license in July 2020.

The problem seems to be related to libfreetype.so.* files in the bin directory. If I don’t remove them, sudo ./install fails and Matlab GUI does not open. If I remove these files, then the GUI opens and I can even enter my email address in the box, but on the next page It does not allow me to type in the password in the password box. The fonts also appear slightly distorted in the GUI.
